HIRAM E. 'CHUTE, OF YARMOUTH, NOVA SCOTIA, CANADA.

ORGAN-CASE.

SPECIFICATION forming part of Letters Patent No. 416,993, dated December10, 1889.

Application filed September 4, 1889. Serial No. 322,940. (No model.)

To all whom it may concern..-

Be it known that I, HIRAM E. CHUTE, of Yarmouth, in the county ofYarmouth, Province of Nova Scotia, Dominion of Canada, have invented anew and useful Improvement in Organs, of which the following is a full,clear, and exact description.

My invention relates to an improvement in organs, one object of myinvention being to provide an organ-casing with a fall-board orkey-board cover, which may be opened by the depression of the pedals ina noiseless and easy manner without interference with the other parts ofthe organ.

A further object is to furnish an organ with means for the automaticclosure of cracks around the pedals when the fall-board is closed,whereby dust and vermin-such as mice, roaches, or spiders-are excludedfrom the interior of the instrument.

' With the objects mentioned in view my invention consists in certainfeatures of construction and combinations of parts, which will bespecifically described, and point-ed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which Figure 1 represents a front elevation, and Fig. 2 a sideelevation, of an organ-casing in section, exposing certain interiorparts common to well-constructed organs, and my improvements combinedwith the casing, so as to avoid interference with the organ mechanism.

A is the casing; A, the front board opposite the key-board; B, thebellows-chamber, the bellows being removed; E, the key-board; D,thekey-bank; b, the swell-action pull-button, and O the upper fixed frontof the organcasing.

The parts named are such as are found in well-constructed organs of anymake, and are here shown to render the construction and relativeposition of novel features of my invention more readily comprehended.

The fixed upper fropt piece 0' of the organcasing A is inclined, so asto project its lower edge f outwardly a proper distance. The verticalwall I, against which the keys D impinge when in normal position, is ofsuch a relative height that a throat between its upper edge and theadjacent loweredge of C is produced.

A cylindrical roller e is preferably journaled in each side of theorgan-casing within the throat just mentioned, which roller is of suchdiameter as to allow space above it for the sliding introduction of thefall-board C.

As will be seen, the fall-board consists of a piece ofmaterial-preferably hard wood boardi inished to suit the style of theorganthe front piece casing and proportioned in thickness t-h roughoutits area, so as to permit it to slide over the roller 6 close to theedge of the front piece 0'.

When the fall-board C is located as shown in full lines in the drawings,its forward depending piece 0 will rest on the upper edge of the fixedfront board A, and the rear portion near the adjacent rear edge willhave support on the roller 6, so that a neat close finish is providedfor the sliding fall-board.

Two pedals J, as usual, are employed to operate the bellows, and areshown in position in Fig. 1.

At equal distance from the vertical sides A of the casing A twopedal-brackets A are secured, which have their rear edges an extendedinwardly beyond the front wall B,as shown in Fig. 2. The pedals J arehinged at their lower front edges upon the rocking board H, which latteris extended across the space between the brackets A and adapted tovibrate by its pivotal connection 1' therewith produced near the lowerfront edge of the board. From the connection made between the pedals androcking board they will move upwardly together on the fulcrum-bolt t',and the board can be depressed by a pressure on either pedal. A low wallit projects upwardly from the rear edge of the board H at a right anglethereto, and corresponding flanges m are formed on the rear edges of thepedals to aiford toe-rests for the feet of the performer.

Near the rear edge of the rocking board H, that projects beyond the rearvertical edges a of the pedal-brackets A atransverse bar 19 is secured,which projects from each side of the board H toward the casing so as tonearly touch its sides, for a purpose which will be explained.

An angle-board K extends across from one pedal-bracket to the other, andby reason of the position it is given the depending portion a of thesame is adapted to meet the upturned wall 70, that projects from thehinged piece H, thus closing up the opening provided for the pedals, oreither of them, to move in.

A strap or other suitable connection 7L is affixed to the rear edge ofthe pedals J ,which strap extends upwardly between the depending flangeu of the angle-board K and the upturned wall 7a to the top portion ofthe bellows-chamber B, passing over the pulley h, and thence rearwardlyto be attached to the bellows when the latter is in position for suchconnection.

At each side of the organ-casing a bellcrank lever G is pivoted to thesides, said pivoted connections being effected near the ends of thelimbs G at Z). The lower ends of the bell-crank limbs G are connected tothe bar which extends from p, the hinged piece H by the connecting-rodsI, which rods are pivoted at one end tothe latter-named piece, and bytheir upper extremities to the limbs G at 0, so that a depression of thepedals J, which correspondingly lowers the hinged piece H, will rock thelevers G toward the rear side of the casing A and cause them to assumean upright position, as shown in dotted lines. A hinged connection ofthe fall-board C to the upper ends of the lever G is formed by pivotinga block 25 on each lever, as at (Z, the proj ecting portions of theseblocks being secured at. g to the fall-board, as shown.

111 operation it is apparent that a depression of the pedals J willpress the hinged piece H downwardly and rock the levers G rearwardly,which movement slides the fallboard over the roller 6 until it assumesthe position shown in dotted lines.

\Vhen the instrument is to be closed, the operator grasps the dependingpiece 0 of the fall-board O and draws the latter forwardly, its weightcausing it readily to assume the position shown in full lines.

Upon closure of the organ, as stated, the close contact of all movableparts of the pedal-action prevents the ingress of mice, dust, orinsects' Having thus described my invention, I claim as new and desireto secure by Letters Patent 1. The combination, with a casing and apedal, of a hinged piece that is depressed by the pedal, a bell-cranklever, a connectingrod, and a fall-board, substantially as set forth.

2. The combination, with a casing, a pedal, and an angle-board affixedto the casing above the pedal, of a hinged piece which is de* pressed bythe pedal, a connecting-rod, a bell-crank, and a fall-board,substantially as set forth.

The combination, with a casing, a pedal, and an angle-board afiixed tothe casing above the pedal, of a hinged piece which is depressed by thepedal, a connecting-rod, a bell-crank, a roller, and a fall-board,substantially as set forth.

at. The combination, with a casing, a pedal hinged to a piece having aprojecting wall, and an angle-piece which is adapted to be met by thewall of the hinged piece, of a.

connecting-rod, a bell-crank, a roller, and a fall-board, substantiallyas set forth.

5. The combination,with a casing, a pedal, an angle-piece, and a hingedpiece having a projecting wall which impinges on the depending portionof the angle-piece when rocked upwardly, of a connecting-rod, abellcrank lever, a roller, and a fall-board hinged to the bell-cranklever so that the fall-board will be moved rearwardly over the rollerwhen the pedal is depressed, substantially as set forth, I

-6. The combination, with a casing, an anglepiece one portion of whichprojects downward, and a hinged piece having an upwardly-projecting wallthat touches the angle-piece when rocked upward and presses against thestrap h, of a pedal-piece having hinged engagement with the hingedrocking piece, a connecting-rod that is pivoted on one end of atransverse bar affixed to the rear portion of the hinged piece and alsoto a pivoted bell-crank, a bell-crank lever, a transverse roller, and afall-board which is adapted to slide on the roller and is hinged to theupper end of the bell-crank lever, substantially as set forth.
